I misquoted and wrote なっちゃう instead of なっちゃって. How does that change the sentence? In examples I've found, -te is always used with "iru" or "kudasai" or other words following it. The sentence " 駅から歩けなくなっちゃって" actually ends with an ellipsis so it could be that there is supposed to be another word.

The て form of a verb can also add the meaning of "and" after the verb. In this case, it's being used to soften the sentence my making it trail off. It makes excuses sound more hesitant and regretful. "Unfortunately I won't be able to walk from the station..."

Heating up some old coffee: Is it possible to make an adverb for the potential "positive" form (instead of the negative one)? Like 歩けなくなる but just for positive? Or do you have to use ように instead?

+1 for the reason that you explain ～ちゃう and ～ちゃって in a single sentence. For a while it was a foreign construct that Google Translate just couldn't educate me on, but now I understand it -- thank you!
